Output to JBOSS_CONSOLE_LOG should be Appended to allow Truncate for Log Rotation

The init scripts (jboss-as-domain.sh and jboss-as-standalone.sh) use the BASH redirect operator > to write output meant for the console upon starting the service to, by default, the console.log file. Truncating this file (for perhaps log rotation) whilst the service is running has proven to be ineffective due to this mode of writing.
